About

This Cypress library makes it possible to perform third-party logins (think oauth) for services such as GitHub, Google or Facebook.

It does so by delegating the login process to a puppeteer flow that performs the login and returns the cookies for the application under test so they can be set by the calling Cypress flow for the duration of the test.

Support

Supported identity providers:

Provider Plugin name
Google GoogleSocialLogin
GitHub TBD
Facebook TBD
Twitter TBD
LinkedIn TBD

Usage

  1. Call the declared task with a set of options for the social login flow interaction
  2. Set the cookies for the test flow with the help of Cypress.Cookies.defaults
cy.clearCookies()

return cy.task('GoogleSocialLogin', socialLoginOptions).then(({cookies}) => {
  const cookie = cookies.filter(cookie => cookie.name === cookieName).pop()
  if (cookie) {
    cy.setCookie(cookie.name, cookie.value, {
      domain: cookie.domain,
      expiry: cookie.expires,
      httpOnly: cookie.httpOnly,
      path: cookie.path,
      secure: cookie.secure
    })

    Cypress.Cookies.defaults({
      whitelist: cookieName
    })
  }
})

Options passed to the task include:

Option name Description Example
username
password
loginUrl The URL for the login page that includes the social network buttons https://www.example.com/login
headless Whether to run puppeteer in headless more or not true
logs Whether to log interaction with the loginUrl website & cookie data false
loginSelector A selector on the page that defines the specific social network to use and can be clicked, such as a button or a link 'a[href="/auth/auth0/google-oauth2"]'
postLoginSelector A selector on the post-login page that can be asserted upon to confirm a successful login '.account-panel'

Install

Install the plugin as a dependency

npm install --save-dev cypress-social-logins

Import the plugin

Import the cypress-social-logins plugin definition for the specific social network login you are interested of, and declare a task that performs the login.

Example:

const {GoogleSocialLogin} = require('cypress-social-logins').plugins

module.exports = (on, config) => {
  on('task', {
    GoogleSocialLogin: GoogleSocialLogin
  })
}

Using the social login

Once the Cypress task is defined we can expose a test case that makes use of it. The task will accept an options object with the username, password and other configurations that need to be specified so that the task can navigate through the page properly.

Once the task has completed it will return the list of cookies from the new page. Most likely that these cookies need to be set for the rest of the sessions in the test flow, hence the example code showing the case for Cypress.Cookies.defaults.

describe('Login', () => {
  it('Login through Google', () => {
    const username = Cypress.env('googleSocialLoginUsername')
    const password = Cypress.env('googleSocialLoginPassword')

    const cookieName = Cypress.env('cookieName')
    const socialLoginOptions = {
      username,
      password,
      loginUrl: Cypress.env('loginUrl'),
      headless: true,
      logs: false,
      loginSelector: 'a[href="/auth/auth0/google-oauth2"]',
      postLoginSelector: '.account-panel'
    }

    return cy.task('GoogleSocialLogin', socialLoginOptions).then(({cookies}) => {
      cy.clearCookies()

      const cookie = cookies.filter(cookie => cookie.name === cookieName).pop()
      if (cookie) {
        cy.setCookie(cookie.name, cookie.value, {
          domain: cookie.domain,
          expiry: cookie.expires,
          httpOnly: cookie.httpOnly,
          path: cookie.path,
          secure: cookie.secure
        })

        Cypress.Cookies.defaults({
          whitelist: cookieName
        })
      }
    })
  })
})
